You know when you have those unremarkable days, those periods of time you experience you know you’ll forget tomorrow? It’s either “just another” day at work, another commute, or a Sunday where you had a beer, fell asleep, only to wake up again to realise it was too late to get up so you stayed in bed till Monday? (And no, I don’t make a habit of that. I’m sure to have at least two beers.) Most days aren’t like that for me, usually I can think of one noteworthy event that sets apart one day from the next, but sometimes it’s as if Stuff Happens™ doesn’t.
This morning I realised it’s been a whole year since we saw the first reversed polarity sunspot pair on the surface of the Sun. A year ago, Solar Cycle 23 was running out of steam and Cycle 24 was about to take over. Solar physicists the world over were making predictions, some thought Cycle 24 was going to be a “doozy”, others were a little more conservative, saying it might just be an “average” cycle. However, 12 months on, it would appear Cycle 24 is off to a very lazy start. Once again, we have a “blank” Sun, a perfect sphere, looking like a marble, or as my wife observed: a jawbreaker (or as us Brits like to expressively call them, gobstoppers).
The stunning image above was shot by skilled astrophotographer Stephen Sykes, over at AstroSlacker.com, demonstrating what superb views of the Sun can be captured by amateur astronomers. When I (eventually) get my telescope, and/or a new camera, the Sun will be my first astronomical object to observe, but I doubt I’ll get as good a view as this.
So, another day, another featureless Sun. That’s not to say it’s been a totally boring year; we’ve had flares from “left over” active regions from Cycle 23 and we’ve had a bit of action from Cycle 24 (the most recent set of spots–Sunspot 1010–have just rotated out of view), and I’m pretty sure this time next year we’ll be inundated with sunspots… fingers crossed (I can’t wait to see some coronal loop arcades again). For now, good night our lazy Sun, I look forward to seeing more action in the coming months…
This day has been a long time coming. Ever since the beginning of Solar Cycle 24 back on January 4th 2008, solar physicists have been eagerly awaiting the fireworks to begin… alas, the Sun decided to take a break and stay blank for nine months, keeping any Cycle 24 sunspot activity hidden. That’s not to say there have been no sunspots. Due to a strange quirk in solar activity, the previous cycle took some time to wind down and continued to send groups of spots to the surface, occasionally unleashing some surprise flares and coronal mass ejections (CMEs).
However, it has now been confirmed that the sunspot group seen today by the Solar and Heliospheric Observatory (SOHO) and international amateur astronomers do in fact belong to Cycle 24.
Just as we were getting concerned that the Sun may be facing an extended solar minimum, amateur astronomers, in the last few hours, have observed a new sunspot pair appearing around the Sun’s south-eastern limb. They are young, emergent spots, gradually getting larger. It will be interesting to see how they evolve. The observation above was taken by Pavol Rapavy in Rimavska Sobota, Slovakia, and now we have detailed images of the region by a British astronomer too (sounds like the Sun might be making an appearance for the UK summer at last!)… Continue reading “Breaking News: We Have Sunspots, First for Over a Month”
